MACHINE Fen FILLING ensslc'son TIRES.

Bufialo, in the county of Erie and State of New York, have invented certain new and. useful'lmprovements in Machines'ior Filling Fabric for Tires, of which the following is a specification.

This invention relates toflmeans for 1111- i pregnating woven fabrics with a liquid or semi-1i ui'd. composition, such as e rubber solution, or the purpose of rendering the fabric waterproof, and improving its Wearing qualities.

' The invention has especial reference to ap-' paratus for filling an enmileffebric which is su'bstantially U-sheped in cross section, and 1s prepare for use as the base or reinforcing portion of the shoe or tread 'mcinber of a so-- through a pleted tire shoe having tion which is adapted to be filled by the ham proved apparatus.

to confine on the wheel rim an in ated air space 01' 3134) called clencher tire, the said shoe havin flanges at its edges adapted to engage m r. flanges on a Wheel rim, the shoe bei formed thbe'. The invention consists in the improvements hereinafter described and claimed.

The same letters of reference indicate the same partsin all the figures. My improved dpparatus comprises two mold members of annularform; vi z., en oute member ,12 andsn inner member 13, said members beiuqformed to crests an annular id cavity-14 c rresponding in form to the annular fabric to be filledfthc cavity ir this case being adapted to contain and fit the outer and inner surfaces of a woven fabric 15 shapcd to serve as the base or inner portion of a tire shoe which is formed in cross section as represented in Fig. 4, and is composed in purl; of the fabric base 15, and in part or": a rubber tread portion 16 applied tothe ou er surface of the fabric base and vulcanized thereto.

ric base 15 is prefereb y thickened at its cell-; I

tr'al portion by an increased number of plies formed at said-portion to tion of the tire increased t tim The outer me'mberlZ is made in two separable section's detachably secured toge'ther by bolts 17,v as shown in 1', or by other'suitsble means, and is prefers. ly adapted heating agent. Inthe ,presentcase I have shown the member 16 provided with steam spaces or chambers 18, which are suitably -'connected so that steam admitted to one chamber through an inlet pipe 19 will circulate through the other chamber and pass therefrom through an outlet pipe 20, ausuitable drip pipe 21 being provided for the es cepe of ater of condensation from the lower portion of the lower chamber. The outer member 12 is provided with a suitable number of supply conduits 22 which conduct the filling composition-fro a suitable reservoir to the outer surface of th fabric 15. The i11- ner'm ember 12is provided with a suitable number of conduits 23 which deliver the fillmaterial to an annular chamber 24'formed inthe inner member, said chamber having numerous radiating outlets 25 which deliver the material to the inner surface of the fabric-l5. Suitable'sup ply ipes areconnected with the conduits 22 end ing flexible sections 26 which are so 'ciently flexible to permit the relative movements of the mold members hereinafter described.

The outer member 12' is yoke supported' by a 27, the central portionof which is to be internally heated by steam or other" ive the outer por- 7 hickness and duraa mounted'on a fixed vertical-stud orbearing 28, the edapte to turn on vided with a shoulder .29 supporting the yo and the member 12. Th e inner membe'r has a flat central or hub portion inwhich is formed an-a erture which surrounds the st liub portion resting on a shoul er .1

30, which is preferably the upper end of n.

28, the said he and the outer member 12 being? said stud, which isprol collar eflixed to the stud 28. The c0llar'31 allixul to the stud 28 above the hub portion of the inner member 13, bears on the uppzr side of said hub portion, the inner memr being adapted to turn between the said: col

lars andu'pon the stud 28.

position being forced into the conduits under' Mechanism is provided for turning the members 12 and 13 simultaneously in opposite directions, and for reversing the movement so that each member has a forward and backward partial rotation, the movement of each being opposite that ol' the other. 'lliese movements of the me1 n.bers l2 and 13 dis-- tribute the filling material supplied by the conduits 22 and 23 over the outer and inner surfaces of the fabric 15. The incchai'iism here shown for moving the mold members comprises two vertical rock shafts 32 jonrnalecl in fixed bearings, and resting on steps 33 at the bottom ends of the lower bearings.

Each rock shaft is provided with two oppo sitely-extending arms 34 35 at its upper end, the arms 34 projecting between studs 36 alfixed to and projecting downwardly from the outer member 12, while the arms 35 project between studs 37 affixed to and projecting downwardly from the inner member 13. To each rock shaft is aflixed a lower arm 38, which is connected by a pitman 39 with an eccentric wrist pin 46 on a face plate 41 at fixed to a driving shaft 42. The rotation of the shaft 42 imparts a rocking movement through the pitman 39 to the rock shafts 32, and these impart forward and backward p artial rotary motions to the mold members 12 and 13.

The operation of the a paratus is as follows: Th'e upper sectiono the outer member 12 is raised from the lower section to permit the insertion of the fabric 15 in the lower sec tion of the member 12. The inner member 13 may be adapted to be raised to facilitate the location of the fabric in its proper place.

The lower side of the fabric being properly located between the lower sides of the outer and inner mold members, the upper section of the outer mold member is lowered to place,

and properly locates the upper side of thefabric. The sections of the outer member 12 are then fastened together by the bolts 17, and the filling composition is admitted through the several conduits, the said com,

a suitable degree of pressure by means not shown. The composition is thus supplied to the outer and inner surfaces of the fabric, and caused to penetrate the same, the above-described motion imparted to the members 12 and 13 distributing the filling composition, and causing it to enter different portions .of the surfaces of the'fabric. When the fabric has been suitably impregnated, the upper section of the outer member 12 is raised, and the fabric removed for subsequent treatment, including the addition to it of the tread portion 16 and the vulcanization of said tread portion and of the filling composition .It will be seen that the inner mold member 13 is supported wholly outside the mold cavity, so that the sald cavity.is not obstructed in any Way, and is open at all parts.

A filling apparatus comprising an annular mold composed of an outer member and an inner member, said members having annular cavity-lorming faces, supporting means for the inner member wholly outside the mold cavity, the latter being entirely unobstructed, and means for ,(fwllllLlCl lllg lilling material to the said cavity.

4,. A filling apparatus comprising an annular inold coi'uposed of an outer member having separable sections, an inner member located betvmen said sections, means forrotatively supporting said mei'nbers, means for conducting filling material to the cavity formed by said nn-mbers, and means for rocking or oscillating the members.

5. A filling apparatus comprising an annular mold composed of an outer member having a yoke, and an inner member having a central hub, means for conducting filling material to the mold cavity, fixed bearings supporting the said. yoke and hub, and means for rocking or oscillating the members.

' (l.
